Dragonshards

Dragonshards appear in three distinct forms, each associated with and originating in a different part of the world. These crystal fragments can be shaped and used to power magic items, artifacts, and constructs, or to enhance the abilities bestowed by dragonmarks.
All dragonshards appear as translucent rock or crystal with swirling veins of color suspended within them. The veins are reminiscent of dragonmarks but are not copies of them, and the pulsating veins make the stones look almost alive. Though dragonshards are translucent, the glowing veins running through them lend their color to each crystal.
Siberys dragonshards fall from the Ring of Siberys that forms a broken path across the night sky. A pulsating swirl of golden veins glows within the crystalline depths of a Siberys dragonshard.
Khyber dragonshards are found deep in the earth, near layers of magma. These living crystals typically grow on cavern walls. A Khyber dragonshard has writhing, midnight blue to oily black veins running through it.
Eberron dragonshards are buried in the shallow soil of the world and are usually found encased in geodelike stone eggs. An Eberron dragonshard has crimson, blood-red swirls churning within its crystalline surface.
